(0,1,2,3,4,5,6,7,8) से repetition बिना (5)-digit even numbers बनाते समय (0) last digit case में count क्या होगा?
Using (0,1,2,3,4,5,6,7,8) without repetition, what is the count for (5)-digit even numbers when (0) is the last digit?
Explanation opens after your attempt
A. \(^{8}P_4\)
Concept
When the last digit is fixed as (0), the remaining (4) places use ordered selection from (8) non-zero digits. In exams the zero-last case removes the leading restriction.
Why this answer is correct
The correct answer is A. \(^{8}P_4\). When the last digit is fixed as (0), the remaining (4) places use ordered selection from (8) non-zero digits. In exams the zero-last case removes the leading restriction.
Exam Tip
Last digit (0) fix होने पर बाकी (4) places में (8) non-zero digits से ordered selection होता है। परीक्षा में zero-last case leading restriction हटाता है।
